SparseSolve(_:_:_:_:_:)

Solve Ax=b using the specified iterative method for complex double values.

Declaration

func SparseSolve(_ method: SparseIterativeMethod, _ A: SparseMatrix_Complex_Double, _ b: DenseVector_Complex_Double, _ x: DenseVector_Complex_Double, _ Preconditioner: SparsePreconditioner_t) -> SparseIterativeStatus_t

Parameters

  • method:

    (Input) Iterative method specification, eg return value of SparseConjugateGradient().

  • A:

    (Input) The matrix A to solve the system for. Only used for multiplication by A or A^T.

  • b:

    The right-hand side b to solve for. If A has dimension m x n, then b must have length m.

  • x:

    On entry, initial guess for solution, on return the solution. If A has dimension m x n, then x must have length n. If no good initial estimate is available, user should set the initial guess to be the zero vector.

  • Preconditioner:

    Type of preconditioner to create and apply.
